Re: [PATCH] drivers: staging: lustre: lustre: include: add "__attribute__((packed))" for the related union

I made a quick and dirty sparse patch to check for this.  I don't think
I will bother trying to send it to sparse upstream, but you can if you
want to.

It found 289 unions which might need a __packed added.  The lustre
unions were not in my allmodconfig so they're not listed.

Perhaps there could be a command line option or a pragma so that unions
will work in the kernel.  We don't care about linking to outside
libraries.

regards,
dan carpenter
